However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
From a career standpoint, the term âbiologistâ can have many meanings. As a biologist, you might study plants, animals, people or a particular environment. You could work in marine biology, wildlife biology or biochemistry, travel to the Brazilian rain forest to study biological compounds or work in a clinical laboratory as a microbiologist.
Education and Salary. Working as a marine biologist typically requires as least a master's degree. Those with only bachelor's degrees typically land non-research jobs such as lab assistant. Aspiring marine biologists should first get an undergrad degree in a general science such as biology or zoology.
